Hầu hết thợ làm móng đều từng gặp tình trạng rỉ sét trên dụng cụ làm móng bằng kim loại của mình vào một thời điểm nào đó trong sự nghiệp.
Rust is a common concern since many people grew up hearing stories about how a rusty nail or other pieces of rusty metals can cause infections such as tetanus. That is a myth… rust does NOT cause tetanus or any other type of infection. Tetanus is caused by a bacterial infection. If these bacteria get deep into the skin, this can lead to a severe infection. But this can just as easily happen with a rust-free nail! Some people are infected with these bacteria by puncture wounds from thorns on plants such as rose bushes. Even so, rust is NOT a pathogen and rust is NOT toxic.
What is rust? The word itself comes from the German word for “red”. About 1200 BC iron began to replace bronze for the making of tools and weapons. The Roman historian and philosopher Pliny the Elder hypothesized that the Gods had created rust to limit the destructive power of iron weapons… which we know now is a rather silly notion. That’s not surprising since the ancients had made lots of silly notions and didn’t have much understanding of the world around them.
Rỉ sét là do nước và oxy kết hợp với nhau để oxy hóa sắt thành oxit sắt. Rỉ sét là một loại oxit sắt. Nước là thủ phạm chính gây ra quá trình oxy hóa này. Các kim loại khác cũng có thể bị oxy hóa. Ví dụ, đồng và đồng thau sẽ tạo thành lớp gỉ màu trên bề mặt của chúng do quá trình oxy hóa. Khi sắt bị gỉ sét, rỉ sét chiếm nhiều không gian hoặc thể tích hơn, gây ra sự giãn nở. Khi quá trình giãn nở này tiếp tục, kim loại tách thành nhiều lớp và bong ra khỏi bề mặt.
This creates pitting and more flaking which leads to more rust formation of freshly exposed metal surfaces in contact with water and oxygen. This leads to the corrosion that is typically seen when metal rusts. Since steel is made mostly of iron, it is no surprise that steel nail implements are corroded by rust when exposed to water and oxygen, unless proper care is taken. That’s why it is important to completely dry all metal implements and keep them in a dry location. This will also prevent the growth of pathogens since they require water to live and reproduce. Therefore, keeping metal implements clean and dry has many benefits.
